SECURING ELEMENT FOR COMPOSITIGN SHINGLES.

Application filed March 2, 1925. Serial Ito. 12359.

I '0 all whom it may c0acem.-'.

Be it known. that I, FRANK. VANnnvEN, a citizen of the United States,residing at Grand Rapids, in the county of Kent and State of Michigan,have invented certain new and useful Improvements in Securing Elementsfor Composition Shingles, of which the following is a specification.

My invention relates to improvements in the manner of laying andsecuring composition shingles upon roofs, and its objects are: first,'toprovide a means whereby the corners and center of the shingles, at thelower ends, may be positively insured against the danger of a heavy windpassing under them and raising them from their proper bearings upon thesurface of the next preceding row of shingles; second, to provide ameans whereby the sidewise expansion and contraction of the shingleswill be fully provided for; third, to provide a means whereby thesecuring elements will be sufiiciently rigid to avert the danger of thir being bent or becoming unreliable by re son of any strain that mightbe forced upon them by the action of heavy wind passing under the lowerends of. the shingles; fourth, to provide securing elements that whenpassed under the edges of the shingles will not raise the shinglesperceptably from the roof boards, and that will not form unsightlyridges in the shingles, and, fifth, to provide securing elements for theshingles that may be properly enameled and arranged to give to the roofan artistic and ornamental finish.

I attain these objects by the construction and arrangement of partsshown in the accompanying drawing, in which Fig. 1 is a plan of theblank from which my securing elements are made. Fig. 2 is a plan of acompleted securing element.- Fig. 3 is a perspective end view of saidelement from the upper end thereof. Fig. 4 is a plan of a part of a roofshowing how the shingles are secured to the roof with my securingelements, and, Fig. 5 is an edge view of the securing element.

Similar reference characters indicate similar parts throughout theseveral views.

My invention consists of a sheet metal securing element of practicallythe form shown in Fig. 2, having the body part 1, a

clamping tongue 2 cut from one end of the body, a strengthening rib, Vformed, struck upwardly in the body 1, and curved slots 4 formed in theother end of the body.

This supporting element is applied as follows: First, it is firmlysecured to the roof by means of nails, or other securing elements passedthrough the slots 0 into the roof boards. The flap or metal over theslots 4 should be sprung upwardly suiticiently so the corners of theshingles may be readily passed into the slots, as indicated at a in Fig.4:, and I prefer that the clamp 2 be slightly curved, as shownin Fig. 5,so that when hammered down upon the surface of the shingle it willpenetrate it slightly for the purposes: first, of securing it so firmlyto the shingle as to avert any possible danger of its being bentupwardly and allowing the shingle to become loose and unsupported atthis point, and, second, to insure so close a connection between thesurface of the shingle and the clasp as to positively prevent anypossibility of Water percolating through between the clasp and thesurface of the shingle. When the securing element is properly secured tothe roof of the building, the clasp 2 and the metal over the corners ofthe shingles, at 4, should be struck a sharp blow with a hammer toproperly embed them into the surface of the shingle.

In laying the shingles upon this securing element the lower edge of theshingle, 5, is passed into the slot 4 with the edge of the shingle closeto the lower line of the rib 3, and the securing elements, as nails,with which the shingles are secured to the roof boards, should be setwell in from the edges of the shingles, as indicated at Z), to givesufficient room at each side of these points for the free expansion andcontraction of the shingles without too much space between the pointsI). The center of the lower edge of the next succeeding row of shinglesis placed under the clasp-2 and the corners in the slots 4 so that boththe centers and the corners of the shingles are held firmly in place. 5indicates the outline of the upper ends of the shingles.

It will be readily understood that if itis desired to utilize mysecuring elements. to add an ornamental finish to the roof, it

menses will be, only, necessary to enamel, paint or otherwise finish theribs 3 and the end 4- in any color or design desired.

Having thus fully described my inven tion, What 1'. claim as newin theart, is:

1. In an element for securing composition shingles to a. roof, a thin,narrow, 0hlong sheet of material laid under, and lengthwise of theadjacent edges of the shingles and having curved diagonal slots in thelower end to receive and secure the lower corners of 'adjacent shingles,and a lip formed at the upper end adapted to interlock with the centerof the lower end of the next upper shingle.

2. In an element for securing the ends and edges of compositionshingles, a thin,

narrow, oblong body having slots in one end to receive and hold thecorners of the shingles and a; centrally formed strengthening rib formedlongitudinally of the body.

3 in an elementfor securing the ends and edges of composition shinglesto the roof of a building, a thin, narrow, oblong body having slots inone end for the reception of the corners of shingles, a strengtheningrib centrally located in said body and extending longitudinally thereof,and n clasping lip cut into the other end of said body in the directline of said strengthening rib, for securing the center of the lower endof each shingle,
